This IT-grade cable organizer keeps your rack cables neatly bundled for tidier rack space. The 0U cord organizer features a combination of D-ring hooks and pass-through holes that enable you to run cables to and from your equipment through the panel and into the hooks. Save Space The 0U rack-cable manager makes it easy to organize cables on your 19-inch 20U or larger server rack without taking up valuable space. It features fifteen D-ring hooks to hold and guide cable bundles running vertically and horizontally. Easily Organize The cable management system consists of one 3 ft. panel that can be installed without tools, using the keyhole-shaped mounting holes found in most racks. Each panel can be installed end to end (top to bottom) to span the height of the rack, or on either side of the rack (front and back). Vertical setups guide cables between equipment mounted at different heights. Protect Equipment This metal cable hanger routes your cables through a panel, reducing tension on equipment ports and preventing damage to expensive rack-mounted devices. Properly routing network, patch, ethernet, and computer cables also improves airflow in your server rack, which helps to keep your equipment running at optimal temperatures to reduce the probability of heat-related damage. The CMVER20UD is backed by a 2-year StarTech.com warranty and free lifetime technical support.
